A very restricted species, this snail has an EOO of 5 km² and an AOO of 4 km², and is known from only 2 locations. Within this limited range, invasion by Cinnamomum verum plants is an ongoing threat, resulting in habitat degradation.
|Range Description:||This snail species is endemic to the Seychelles islands of Mahé and Silhouette, and is found in an elevational band from 540-600 metres above sea level. Its area of occupancy (AOO) is estimated to be only 4 km², while its extent of occurrence (EOO) is only 5 km². However, E. moreleti was last recorded on Mahé in 1972, despite surveys looking for this species since then, it has not been found.|

|Population:||The population was estimated at 84,000 individuals in 2005.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||Restricted to high forests from 540-600 m, this snail is found in the axils of Dracaena reflexa and Pandanus hornei plants. It is the only streptaxid known to be herbivorous, feeding on algae and detritus. An ovoviviparous species, it produces eggs but retains them inside the female's body until hatching occurs.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Major Threat(s):||This snail is threatened by habitat deterioration, caused in the past by small-scale wood plantations and currently caused by invasion by Cinnamomum verum plants.|
|Conservation Actions:||No conservation actions are in place. Legal protection of Silhouette island is required to protect the main popualtion.|
